paq

paq implements a subset of Browserify's features with full multithreading support. For impatient people who have to deal with large codebases.

What's Working

• require('./relative/path')
• require('some-module')
• require('node-core-module')
• require(path.join(__dirname, 'some_module')) (or any other statically resolvable expression, like __dirname + '/path')
• Exporting a standalone bundle
• Converting transforms like hbsfy for use with paq

What's Not Working

• paq can't actually run transforms yet. The code is written and tested, but I haven't hooked it up to the CLI because I couldn't decide on what the API should look like.
• Replacement of process.env with actual environment vars.

Usage

USAGE: paq <entry files> [options]

Options:
  --parserTasks=<integer>          The maximum number of concurrent AST parsers
  --requireTasks=<integer>         The maximum number of concurrent require
                                   evaluations
  --standalone                     Returns a module that exports the entry
                                   file's export
  --convertBrowserifyTransform     Returns a module that wraps a browserify
                                   transform for use with paq
  --ignoreUnresolvableExpressions  Ignores expressions in require statements
                                   that cannot be statically evaluated

Under The Hood

• Written in Objective-C++
• Uses a native port of the require.resolve algorithm
• Uses GCD for concurrency
• No external dependencies; escodegen and acorn are embedded in the binary
• Decent tests

Caveats

• Mac only for now. If you get it running elsewhere, send a PR.
• Implements only the subset of Browserify that I need at work.
• Browserify is a production ready, well maintained, and mature project. paq is none of those things, considering I wrote it in about 24 hours.

Contributing

To work on paq, you'll need these tools:

• Xcode 6.2
• OS X 10.10.2
• xctool (Get Homebrew then brew install xctool)
• node
• npm

To run the tests (which require the things mentioned above) you can either run npm test from the command line, or run the paq-test target in Xcode.
